IIRC, it's mentioned at at least one point in the first big video on the topic that they haven't tested other manufacturers "'Smart' TVs" but would not be surprised to discover that other manufacturers are doing the same thing. They're not a news organization owned by one of the 0.1%, so they can only do investigation and reporting so quickly.

I'm not sure which video you're talking about.
If you were expecting the recent one that talks about the lulzy ASUS RCE and how it could interact with "'Smart' TVs" to have even more information about "TV" vulnerabilities or consumer-hostile features, then your expectations are out of line.
If you're asserting that you knew nearly everything in the initial "Wow, these LG 'Smart' 'TVs' can really easily become always-on spy devices, and -in some respects- already are!" video, well, okay? There are those of us who know that shady shit is going on because we have ten brain cells to rub together, a moderate level of awareness of the world around us, and can pretty easily connect the dots. It's an entirely different thing to demonstrate that that is going on for the benefit of people who are -for some reason- reluctant to believe that -yes- Big Megacorps do heinous things to their customers in order to make a bit more money because they don't expect to get caught... and even if they get caught, the punishment will only be a tiny fraction of the profit gotten from doing those things.

[0] The biggest irony here is that objections to claims that this is how Big Megacorps typically do business with us Little People are often dismissed as "4D chess" or "conspiracy theories"... but, like, this behavior is a textbook example of a rational economic actor responding reasonably to market incentives. This is the "Invisible Hand Of The Market" at work.
